Let's denote the first term of the arithmetic progression as a and the common difference as d .

1. The sum of the extremes:
Given that the first term plus the tenth term equals 22, we have
a + (a + 9d) = 22
2a + 9d = 22
2a = 22 - 9d
a = 11 - \frac{9d}{2}

2. The product of the third and fourth terms:
The third term is a + 2d and the fourth term is a + 3d .
Given that the product of the third and fourth terms is 48, we have
(a + 2d)(a + 3d) = 48


solvinf equation we get

Answer: d = 2 and a=2 .
